ABSTRACT:
A wrench of the type having one handle member connected to a pivotal arm member at a pivot point. The handle member, and the pivot arm member terminate in a jaw member, the jaw in the handle member being fixed. Advancing a screw member causes the pivot arm member to rotate about the pivot point so that the jaw members are brought together. A pair of slots translate the rotating motion of the pivot arm member about the pivot point into linear components. The jaw member at the end of the handle member and the pivot arm member are biased apart from one another by a spring, but the bias may be overcome by squeezing the handle and pivot arm member or by advancing the screw member. When the screw member is fully retracted, the spring separates the jaw members. When the screw member is advanced, it prevents separation of the jaw members.
